Taiwan-based chipset suppliers Silicon Integrated Systems (SiS) and VIA Technologies will both start volume production of new chipsets supporting dual-channel memory and Pentium 4 processors in September, according to the companies. While SiS will start volume production of its SiS665FX and SiS661FX chipsets in September, VIA expects to start producing its PT880 chipset in small volumes in late September, with major shipments to start in October, companies said.

All three new chipsets will be displayed at Computex 2003, the companies said. Meanwhile, both companies plan to start sampling new chipsets supporting the PCI Express standard later this year. While VIA is set to sample its PT890 in October, SiS plans to sample its SiS656 at the end of this year.

Intel expects to start sampling its new-generation Grantsdale chipset supporting the PCI Express standard and Socket 775 for high-end Prescott processors. The new chipset will be officially introduced in the second quarter of 2004, according to sources at Taiwanese motherboard makers.
